Endemic in coastal areas, rivers and estuaries of Australia. Most abundant in river mouths and estuaries (Ref. 28468, 28472). Inhabit brackish waters of coastal rivers and lakes, occasionally penetrating fresh water (Ref. 44894). Considered as the only true estuarine sparid in Australia. Larvae and small juveniles are most abundant over seagrass beds in shallow estuarine waters (Ref. 28468, 28472). Spawning period varies considerably between estuaries (Ref. 28468). Remain upstream in sheltered waters to spawn and is not usually found in purely marine habitats (Ref. 44894). Feed on shellfish, worms, crustaceans, small fish and algae. Sold as whole, chilled products in domestic markets (Ref. 6390). One of top angling species in southern Australia (Ref. 6390, 44894), as well as being a delicious table fish (Ref. 2156).
澳洲的沿岸区域，河与河口的特有种。 最丰富在河口与河口.(参考文献 28468,28472) 栖息于沿海的河川与湖的半咸淡水域, 偶然地穿透淡水.(参考文献 44894) 被当作在澳洲唯一的真实河口的鲷科鱼类了。 仔鱼与小的稚鱼在水浅的河口水域中是最丰富的海草床之上。 (参考文献 28468,28472) 产卵时期在河口之间改变很大。 (参考文献 28468) 向上游在有遮蔽的水域的残余物产卵而且是发现于不常的纯粹海洋的栖息地。 (参考文献 44894) 捕食贝，蠕虫，甲壳动物，小鱼与藻类。 整隻販賣, 在國內市場中的冷凍產品.(參考文獻 6390) 在澳洲 (參考文獻 6390,44894) 南部的頂尖釣魚種之一, 以及有一個可口的食用魚.(參考文獻 2156)
